Please refer to Fig. 9 to Figure 11, now end face processing is carried out to optical fiber and rapid-assembling time, first the joints of optical fibre 100 are placed between a pair first clamping parts 305 and a pair second clamping parts 306, first clamping part 305 holds shell 53 one end away from tail cover 70, and the second clamping part 306 holds shell 53 one end near tail cover 70.Then groove 531 is run through from a pair second in a pair holding section 3033 of shifting part 303 and stretch into the joints of optical fibre 100, holding section 3033 is run through groove 511 two pairs of clamping parts 262 that are rear and locking part 26 through first and is supported, meanwhile, the support division 264 of locking part 26 is sticked in the slot 3034 of shifting part 303.Operator's shifting part 303 that slides runs through groove 511 along first and moves towards one end near the second installation portion 226 of fixed part 222, shifting part 303 drives locking part 26 to slide, locking part 26 compresses holder 24, and the second supporting surface 2442 of holder 24 is moved towards the bottom of the accepting groove 2220 of fixed part 222, lock hole 2622 on locking part 26 and projection 2224 engagement release on fixed part 222, second supporting surface 2442 of holder 24 compresses the bottom of the accepting groove 2220 of fixed part 222, thus locking part 26 removes locking fixed part 222 and holder 24.Take off tail cover 70, then optical fiber 80 is inserted optical fiber clamping mechanism 20 from the end of tail cover 70.Now the first supporting surface 2422 of holder 24 tilts, thus makes to occur certain gap between the second locating slot 2424 and the first locating slot 2222, and fibre core 82 passes through optical fiber clamping mechanism 20 via guide channel 2446 and described gap.Continue to insert optical fiber 80 to fibre core 82 to stretch out from fiber stub 10.In present embodiment, the fibre core 82 of optical fiber 80 extend out to roughly between pair of discharge electrodes 503 from fiber stub 10.
Please refer to Figure 12, actuator 308 drives push piece 307, owing to being provided with elastic component between actuator 308 and push piece 307, the pushing and pressing end face 3071 of push piece 307 flexibly supports pushing and pressing fiber core 82, and the end face of fiber core 82 is contained in holding tank 3073.Actuator 308 is urged to and is accurately positioned (to refer to Fig. 7) between pair of discharge electrodes 503 in the end of fibre core 82, and now, assembled fixture 300 is positioned at the first state.Start end face treatment facility 500, sparking electrode 503 discharges and carries out discharge process to the end face of fiber core 82.After electric discharge, actuator 308 continues to drive push piece 307 to flexibly support fiber core 82 and offsets (referring to Figure 10) with the end face of fiber stub 10 to pushing and pressing end face 3071, and now assembled fixture 300 is positioned at the second state.Then actuator 308 drives push piece 307 to be repositioned to initial position.Now, the length that fiber core 82 stretches out fiber stub 10 end face equals the degree of depth of holding tank 3073.
Please refer to Figure 13, operator's shifting part 303 that slides runs through groove 511 along first and moves towards one end near the first installation portion 224 of fixed part 222, shifting part 303 drives locking part 26 to slide, locking part 26 compresses holder 24, and the first supporting surface 2422 of holder 24 is moved towards the bottom of the accepting groove 2220 of fixed part 222, continue to promote shifting part 303 until the lock hole 2622 on locking part 26 fastens with the projection 2224 on fixed part 222, first supporting surface 2422 of holder 24 compresses the bottom of the accepting groove 2220 of fixed part 222, thus be fixedly contained in the fibre core 82 of the optical fiber 80 in the first locating slot 2222.Then install tail cover 70, the outer covering layer 86 of the end grip optical fiber 80 of tail cover 70, with further fixed fiber 80.
Be appreciated that, locking part 26 only can be arranged with a pair clamping part 262 on a sidewall, support division 264 then between clamping part 262 is also only one, accordingly, sheath body 51 and shell 53 also only can be offered one with clamping part 262 and relative first run through groove 511 and second and run through groove 531, and meanwhile, the holding section 3033 of shifting part 303 also only needs a pair, or slot 3034 is directly opened in main body 3031, and omit holding section 3033.
The joints of optical fibre 100 of the present invention, can lock or unclamp the fibre core 82 of clamping because locking part 26 slides on fixed part 222, clamping part 262 on locking part 26 and support division 264 are coordinated with the shifting part 303 of existing assembled fixture 300, fibre core 82 can be unclamped relatively easily, thus after now the end face of optical fiber 80 being processed, under the cooperation of actuator 308 and push piece 307, now fibre core 82 can will be pushed into desired location, then shifting part 303 drives locking part 26 to clamp fibre core 82, thus can be quick, realize now assembling of optical fiber easily.
Those skilled in the art also can do other change in spirit of the present invention, and certainly, these changes done according to the present invention's spirit, all should be included in the present invention's scope required for protection.
